Varicose veins are a group of diseases of the peripheral blood vessels. The disease not only affects aesthetics but also affects daily life, many cases have to be amputated because of severe inflammation.
1. What are varicose veins?
Chronic venous insufficiency is a common condition caused by reflux of blood in the veins. In the lower extremities, venous reflux can be in the superficial or deep veins. The superficial vein involves the great saphenous vein, the minor saphenous vein, and its branches between the skin and the muscle fascia, and can be treated surgically. Deep veins involve the femoral veins and other deep veins that are located below the fascia and are difficult to treat with interventional therapy.
Mild cases of varicose veins are only uncomfortable or unsightly, but severe can lead to leg edema and eventually ulceration.
2. Causes of varicose veins
Venous reflux occurs when there is a failure of the valves in the veins in the saphenous veins, blocking blood flow in the branches of the saphenous veins. Normally, venous pressure in the extremities is regulated by these valves. Valves that no longer function causes an increase in venous pressure and can cause symptoms. If the blood pumping mechanism in the legs is poor, it can cause more severe symptoms.
3. Symptoms of varicose veins

At that time, the disease caused many complications and it was difficult to completely overcome.
